HOSE-COUPLING.

Specification of Letters Patent.

Patented Feb. '7, 1911.

Application filed May 24, 1910. Serial No. 563,059.

all whom it may concern:

Be it known that I, JorrN E. TV. Benson, a citizen of the United States,and a resident of Columbia, in the county of Esmeralda and Stateof'Nevada, have invented certain new and useful Improvements inHose-Couplings, of which the following is a specification.

My invention is an improvement in hose couplings, and consists incertain novel construetions, and combinations of parts, hereinafterdescribed and claimed.

The object of the invention is to provide a coupling of the characterspecified, which may be quickly connected and disconnected, by pullingthe sections straight away from each other, thus avoiding thedisadvantages of twisting the hose, and wherein an eflicient lock isprovided for preventing accidental disengagement.

Referring to the drawings forming a part hereof, Figure l is a side viewof the coupling with the sections separated, Fig. 2 is a similar view atright angles to Fig. 1, Fig. 3 is an enlarged perspective view partly insection of one section, Fig. 4 is a longitudinal section with thesections coupled, Fig. 5 is an enlarged side view of one section, andFig. 6 is an end view.

The embodiment of the invention shown in the drawings consists ofsimilar sections 1 and 1, each being tubular, and substantiallycylindrical in shape, and having its bore enlarged at the outer end toreceive the hose 2. The wall of the enlargement is undercut as shown at5, and a shoulder 6 is provided between the enlargement and the bore,against which the end of the hose abuts.

At its coupling end, each section'is reduced annularly to form twoannular shoulders 9 and 10, and one-half of that portion of the. sectionwhich extends beyond the shoulder 9 is rabbeted as shown at 7 to form ashoulder 4 on each side of the section, running parallel with the lengththereof. The shoulders 4: extend inside of the annular shoulder 10 asshown in Fig. 3, and each shoulder 41: is provided on its face with adove tail or undercut longitudinal groove a. At the inner end of eachgroove, the shoulder is also transversely grooved as shown at 26, thegroove 26 intersecting the inner end of the groove l.

Each section is provided with a pair of spaced cars 11 extendingoutwardly above the shoulders 9 and 10, and spaced apart from the outerface of the reduced portion, and the ends thereof are substantiallyflush with the end of the section. The ears are transversely perforatedat 12, the perforations being in alinement, and the outer face of eachear is cut away to form a countersink or recess 13, in which theperforation opens, and two openings 14: are provided above the recess. Abolt 15 is adapted to pass through the perforations, the said bolthaving a longitudinal recess 16 in the side all thereof, and a lever 17is secured to each end of the bolt by a screw 18.

lVhen the bolt 15 is engaged with the perforations 12, the lever fitsthe side and end wall of the countersink, and a plate 19 is secured tothe outer face of the car by means of screws 20 engaging the openingsli, and passing through registering openings 21 in the plate. As shownmore especially in Fig. 3, the free edge of the plate is thickened. asindicated at 22, and is provided with spaced recesses 23. \Vhen theplate is in place, the recesses 23 are on opposite sides of the screw18, and are adapted to be engaged by a lug 2 1 on the lever 17, to holdthe bolt in adjusted position. It will be noticed that the plate isthinned transversely at 25 at approximately its center, and being ofresilient material, that portion of the plate on the opposite side ofthe thinned portion from the recess 20 acts as a spring to hold thelever, while permitting the lugs to be easily disengaged.

At a point diametrically opposite the ears 11, each section is providedwit-h a lug 27, whose sides are cut away near its outer end 28 to forman car 29, which is recessed at 30, to form a nose 31, and a lip 32overlying the nose but spaced apart therefrom. The recess 30 is shapedto fit the bolt 15, as shown in Fig. l, and the recess 16 of the bolt isof suflicient depth to receive the nose 31, when the bolt is properlyturned to permit its entrance. The lip 32 overlies the bolt, andprevents lateral movement. The lever 17 is so arranged with respect tothe bolt, that when the lug 2 1 is engaged with one of the openings 23of the plate 19, the recess 16 of the bolt will be out of position forengagement by the nose as shown in Fig. 4, and when the lug 24L isengaged with the other opening 23, the nose will be received in the saidrecess.

A packing section 33 is connected with each of the coupling sections,each packing section being composed of a half-ring 3st having atapproximately the center of its outer face a rib 35, provided with anannular flange 36, and at each end of the section, between the flange 36and the half ring 34: is arranged a bar 37, each of whose faces isconstricted longitudinally at its center at 38 to fit the grooves 4 ofthe shoulder at.

It will be understood that when the coupling sections are connected, thegrooves r of the sections are in register, and the bar 37 is shaped tofit the two grooves. A semicircular gasket 39 is arranged on the outerfaces of the portions 8st and 86 of the packing, the sections beinggrooved at eLO to receive the said gaskets, which assist in retainingthe packings in position.

In coupling the sections, they are moved toward each other in thedirection of the arrows in Figs. 1 and 2, the levers being turned 180from the position shown in Fig. l, or in such position that the noses 31will be received in the recesses 16 of the bolts. As they are pushedtogether, the bolt is rotated by the nose, so that when closely pressedtogether, the lever will be held by the engagement of the lug 2st withthe proper opening 28 of the plate. To release the sections, the freeends of the levers 17 are pulled outwardly, until the lovers are atright angles to the hose, after which the sections are pulled apart. Thelever 17 is partially covered by the plate, so that it cannot be caughtand turned accidentally. The act of coupling is automatic when thelevers are freed, and no turning or twisting of the hose is necessary.

It will be observed from an inspection of Fig. 5, that the ends of thelevers 17 extend beyond the plates, so that they may be moved into suchposition that the nose 3i will engage with recess, after which, bymerely pulling the sections apart, the bolt will be rotated to free thesections. The lever must be moved to a position at right angles to thehose before the sections can be pulled apart, so that there is nopossibility of accidental uncoupling.
